Signature feature doesn't work after upgrade to latest version
After upgrade to the latest version,the Fill and Sign feature stops working.
I can't add Fill and Sign (Sign yourself) tool to the tool bar, the tool button shows on the pop up window when I try to custermise it, but the "save" button is greyed out, and it never shows up the left tool bar.

Please advice on how to solve this bug.
I've reinstall the Acrobat 3 times with no luck, I'm using windows 10 and I also hve the subscribiton for the Adobe createive suit.
Many thanks
